Levels in the three-hole nucleus 105Ag and the decay of 55.5-min 105Cd

The γ-ray spectrum following the decay of 55.5-min 105Cd to levels of 105Ag has been studied by singles, coincidence, and Compton-suppressed γ-ray spectroscopy. Sources were prepared by the (n,2n) reaction on isotopically enriched 106Cd sources using 14-MeV neutrons. A total of 274 γ rays are attributed to the decay of 105Ag, and approx.248 are placed in a level scheme involving 53 excited states. These data along with the results of (3He,d) and (p,t) reaction studies were utilized to make spin and parity assignments for many of the levels. The systematics of the Z=47 silver nuclides are compared with various theoretical calculations and the systematics among the N=58 isotones are discussed
